We report a case of a 17-year-old girl, who presented with symptoms of epigastric and right hypochondrium pain since 1\u2009year. She was afebrile and physical examination revealed a soft, non-tender, firm, bimanually palpable and ballotable mass along right flank. Ultrasound abdomen showed a large heteroechoic mass in right suprarenal region with indistinct planes with upper pole of right kidney. On CT, a large right suprarenal mass was noted with origin likely from right adrenal gland. Surgery was done and intraoperatively, the large mass in right suprarenal region showed involvement of the upper pole of the right kidney. The right adrenal gland was small in size, compressed and displaced by the lesion. Histopathology revealed the mass to be PNET of kidney. We report the relevant imaging findings of the case with review of literature of this entity.<\/jats:p>","DOI":"10.1136\/bcr-2020-235484","type":"journal-article","created":{"date-parts":[[2020,10,4]],"date-time":"2020-10-04T17:15:12Z","timestamp":1601831712000},"page":"e235484","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":0,"title":["Primitive neuroectodermal tumour (PNET) of the renal capsule mimicking solid adrenal tumour"],"prefix":"10.1136","volume":"13","author":[{"given":"Amrin","family":"Israrahmed","sequence":"first","affiliation":[{"name":"Radiodiagnosis, Sanjay Gandhi Postgraduate Institute of Medical Sciences, Lucknow, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Somesh","family":"Singh","sequence":"additional","affiliation":[{"name":"Radiodiagnosis, Sanjay Gandhi Postgraduate Institute of Medical Sciences, Lucknow, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hira","family":"Lal","sequence":"additional","affiliation":[{"name":"Radiodiagnosis, Sanjay Gandhi Postgraduate Institute of Medical Sciences, Lucknow, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Manoj","family":"Jain","sequence":"additional","affiliation":[{"name":"Pathology, Sanjay Gandhi Postgraduate Institute of Medical Sciences, Lucknow, India"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2020,10,4]]},"reference":[{"key":"2025082708530100000_13.10.e235484.1","doi-asserted-by":"crossref","first-page":"196","DOI":"10.1016\/j.clinimag.2009.01.017","article-title":"Imaging findings of abdominal peripheral primitive neuroectodermal tumor: report of four cases with pathological correlation","volume":"33","author":"Gong","year":"2009","journal-title":"Clin Imaging"},{"key":"2025082708530100000_13.10.e235484.2","doi-asserted-by":"crossref","first-page":"449","DOI":"10.1023\/A:1019511205650","article-title":"Primitive neuroectodermal tumor of the kidney: a rare entity","volume":"33","author":"Gonlusen","year":"2001","journal-title":"Int Urol Nephrol"},{"key":"2025082708530100000_13.10.e235484.3","first-page":"151","article-title":"Peripheral neuroectodermal tumors","volume":"2","author":"Seemayer","year":"1975","journal-title":"Perspect Pediatr Pathol"},{"key":"2025082708530100000_13.10.e235484.4","doi-asserted-by":"publisher","DOI":"10.1046\/j.1365-2559.1998.0358a.x"},{"key":"2025082708530100000_13.10.e235484.5","doi-asserted-by":"publisher","DOI":"10.1097\/01.ju.0000065880.06201.5c"},{"key":"2025082708530100000_13.10.e235484.6","doi-asserted-by":"crossref","first-page":"165","DOI":"10.1002\/jso.2930350305","article-title":"Malignant primitive peripheral neuroectodermal tumor of the uterus","volume":"35","author":"Rose","year":"1987","journal-title":"J Surg Oncol"},{"key":"2025082708530100000_13.10.e235484.7","doi-asserted-by":"crossref","DOI":"10.1155\/2010\/987128","article-title":"Renal cell carcinoma mimicking adrenal tumor","volume":"2010","author":"Moslemi","year":"2010","journal-title":"J Oncol"},{"key":"2025082708530100000_13.10.e235484.8","first-page":"1081","article-title":"[Primary neuroectodermal tumor (PNET) of the kidney: 26 cases.
